Techopedia Explains Noise
There are four main types of noise:
- Thermal noise, which is caused by conductor electron agitation and cannot be removed.
- Intermodulation noise, which is caused by non-linearity in communication devices.
- Cross-talk, which is often observed during phone conversations.
- Impulse noise, which is caused by analog signal interruptions, leading to data loss.
